    Abstract: A remanufactured planet carrier is disclosed having a first plate and a second plate spaced apart from and oriented generally parallel to the first plate. Supports join and support the first and second plates. The remanufactured planet carrier further has a plurality of first pin bores in the first plate and a plurality of second pin bores in the second plate. The first pin bores are parallel and generally aligned with the second pin bores. A cylindrical member extends from a central axis of the second plate away from the first plate with a shaft bore formed within the cylindrical member. The first and second pin bores and the shaft bore each have a surface layer with a hardness of at least about 180 BHN and a strength of at least about 500 MPa.

    Abstract: A bearing system includes a sleeve bearing supported on a shaft and a gear supported on the sleeve bearing. The shaft has an outer diameter shaft surface, the sleeve bearing has an inner diameter bearing surface and an outer diameter bearing surface, and the gear has a gear bore surface. At least one of the outer diameter shaft surface, the inner diameter bearing surface, the outer diameter bearing surface, and the gear bore surface includes an isotropic surface finish and a hard thin film over the isotropic surface finish. During a break-in period of operation of the bearing system, the hard thin film over the isotropic surface finish breaks in a counter surface of the bearing system to extend a hydrodynamic lubrication period of operation of the bearing system.

    Abstract: A valve for use in an internal combustion engine is disclosed. The valve includes a stem connected to a fillet disposed between the stem and a seat face. A port receives the stem and accommodates a seat insert that engages the seat face when the valve is in a closed position. The seat insert is fabricated from a non-cobalt-based alloy or an iron-based alloy and the seat face is coated with a cobalt-based alloy or a nickel-based alloy. The coating may be applied using a thermal spray process, such as HVOF.
